HINGE.

Application filed February 28, 1927. Serial No. 171,474

The present inventionrelates to hinges and more particularly to sheetmetal hinges wherein the leaves themselves of the hinge areformed toprovide means taking the place and function of the usual pintle.

'Among the objects of the present invention is a hinge of the typeindicated which is fixed against relatiye longitudinal movement of theleaves and yet free to carry out the Fig. 1 is a cross. section of ahinge connectin for example, a door to its frame;

ig. 2 is an elevation of'the hinge; Fig. 3 isa section of the hinge online 33 I I of Fig. 2 but on an enlarged scale;

Fig. 4 is a section similar to that of Fig.

3 but showing an intermediate stage of the.

manufacture of the hinge.

As indicated in the drawing the hinge for the most part is similar inform and action,

to the hinge described and claimed in copending application Ser. 0.96,65, filed March 22, 1926 by the present inventor, and comprises twoleaf ortions 10 and 11 each being a metal strip 0 a length equal to thelength of the hinge and each secured to the parts to be hinged in anysuitable manner as by screws 13, .ifscrews may be used, or welded, ifmetal to metal contact, or in any other suitable fashion.

The two parts or leaves 10 and 11 are pro 1.

vided 'withlongitudinal beads 20 and 21 which are each substantiallysemicircular in section with the outer edges 22 and 23 turned inwardly,the edge 22 substantially radially of the bead and the edge 23 parallelThe two arcs are such that when the hinge is in closed position, the oneembraces the other as indicated in Figs. 1 and 3 and in suchpositionthese arcs can be considered as described from a common center 50, whichcenter is'located a short distance from the edge 25 of the inturnedportion 22 of bead 2 1. The bead 21 takes the place of and functions asthe pintle of the hinge.

It will be noted that the edge 2-l of the inturned portion 23 extendsbeyond the edge 25 of part 22 and that there is a groove 26 along theformer edge. This groove 26 will be approximately arc;shaped in sectionand is described from the same center 50 as portions 20 and 21, having aradius equal to the distance from this center point 50 to one corner 27of the edge 25.

In the prior application, the hinge is the same as the present one as sofar described, but in ,the prior hinge the twoparts are fully formed andassembled together by sliding the one longitudinally into the other, noprovision being made for vertical mounting or. the "carrying of any loadtending to move the leaves relatively longitudinally.

In the present hinge, the leaf 11, the inner one, is formed as in theprior hinge and is then provided with one or more rectangular notches 30(only one being shown). The leaf 10 is then formed but the inturned end23 not setat the final position, that is, it is turned to about theposition indicated in Fig. 4 so that when the parts 10 and 11 are slidto gether edge 23 will be spaced from edge lVhen the two parts have beenformed as indicated, they are slid together as in the prior hinge but ineach of the notches 30 is 1 placed a pin 31 of the form shown inFig. 2.This pin consists of a short piece of hardened steel rod having fiatends and with circumferential grooves forming a plurality of annularedges 32. And when -thus assembled, the whole is placed ina suitablegrooved (lie or anvil with part 20 in the groove, and

struck with a suitable lined tool or mating 9o 1 die upon edge 23 toforce the latter to the position shown in Fig.- 3, its finishedposition.

This causes the edges 32 of pin 31 to be embeddedin themetal of the bead20 of leaf 10 at several points, for example, at 60, 61 and 62. asindicated in Fig. 3 and with the abutment of the pin ends against theends of notches 30 provides a positive and permanent lock againstrelative longitudinal displacement of the leaves.

The number of pins 31 and their distance apart will depend largely uponthe service required of the hinge,usually, however, they will be spaceda few inches apart and the number determined by the length of the 105hinge. And the diameter of the pins should be large enough to cause theedges 32 to enter the metal of the outer bead but not so large that thenotches 30,'inorder toaccommodate .the pins, will have to be deep enoughto be exposed'when the hinge is closed.

Having now described the invention and the preferred form ofembodimentthereof it is to be noted that the said invention is to belimited not to the specific details herein set forth and illustrated butonly by the scope of the claims whichefollow.

1. In a sheet metal hinge in which the leaves are provided with beadsofwhich one embraces the other a pin fOVidGd with a plurality ofprojecting portlons embedded in mam t 2.111 a sheet. metal hinge inwhich the leaves are provided with beads of which, one

embraces the other and'which are separable only by relative longitudinalmovement, means for. preventing such movement, said means consisting ofa member fixed in the outer bead and abutting shoulders on the innerbead.
